Specification of Letters Patent.

Patented July 22, 1913.

Application filed. October 1, 1910. Serial No. 584,937.

To aZZ tic/10m it may concern Be it known that l, CLYDE C. Lownu, acitizen of the United States, residing at Ashton, in the county of Spinkand State of South Dakota, have invented certain new and usefulimprovements in Engine Speedliegulators; and I do hereby declare thefol: lowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to new and useful improvements in governorattachments for steam engines or the like.

An object of this invention is the provision of a device of thischaracter whereby the valve rod of the governor can be operated and heldin a fixed position, for the purpose of loading or unloading thegovernor and thereby re ulating the speed of the engme.

Another object of this invention is to improve and simplify devices ofthis character, rendering them comparatively simple and inexpensive tomanufacture, reliable and efficient in use, and readily operated.

iVith the above and other objects in view, this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more particularly described,claimed and illustrated in the accompanying drawing, in which- Figure 1is a side elevation of a portion of an engine illustrating my inventionapplied to the governor thereof; Fig. 2 is a detail perspective view ofthe attachment removed; and Fig. 3 is a detail view of the tensionsprings.

Referring to the drawing by characters of reference, the numeral 1designates generally a portion of an engine, upon which is mounted theusual governor 2, consisting of the casing 3, in which is verticallymounted the valve rod 4;, being operated by means of the customary flyballs 5.

The portion of the valve rod within the casing is of the usualconstruction and carries the customary grooved disk 6, adapted to engagethe inwardly projecting portion 7 of a rocker arm 8 mounted in a bracket9 located upon the outside of the casing 3. A flexible connecting member10 is secured to one end of the rocker arm 8 and passes over a pulley 11mounted upon the further side of a quadrant 12 secured to a suitable stationary t art of the engine within convenient reach of the operator.

A hand lever 18 is pivoted as at 14;, to an upwardly extending lug 15carried centrally of the plate 16, which supports the quadrant 1.2, andis held in a fixed position by means of a spring actuated locking pawl17, slid.- ably mounted upon the said lever and adapted to engage thenotches or teeth 18 formed in the upper edge of the quadrant 12. Asuitable handpiece 19 is pivoted, as at 20, to the upper end of thelever 13, and is adapted to be connected with the upper end of the pawl17, for the purpose of operating the same into and out of engagementwith the teeth 18. A flexible member 21 is secured to one of a series ofapertures 22 formed in one edge of the lower end of the lever 13, and isconnected at its opposite end to the lower end of the rocker arm 8. Aseries of tension springs 23 are connected to the inner ends of theflexible member 21 to provide a yielding connection between the beforementioned rocker arm 8 and lever 13.

The opposite end of the flexible member 10 to the one which is connectedto the rocker arm 8, after passing over the pulley 11, is secured to oneof a series of apertures 24: formed in the rear edge of the lower end ofthe lever 13.

From the foregoing disclosures, taken in connection with theaccompanying drawing, it will be manifest that an attachment forgovernors is provided for which will fulfil all of the necessaryrequirements of such a device.

Having thus fully described this invention, what I claim as new anddesire to prot-ect by Letters Patent is:

The combination with a governor com.- prising a rocker arm having twoends, of a plate, a segmentmounted upon said plate, a lever mounted uponsaid plate and co-acting with said segment, a pulley secured to said Intestimony whereof I afiiX my signature in presence of two wltnesses.
